Background technology
Pneumatic conveying drying, be with shot shape solid material dispersion suspension in the high speed thermal current, under strength is carried, carry out dry a kind of method.The characteristics such as have the heat transfer coefficient height, heat transfer area is large, and drying time is short.Pneumatic conveying drying claims that also " wink-dry " is that dilute phase is carried application aspect dry in the fluidization of solid.This method is that heat medium is directly contacted with solid particle to be dried, and solid particle to be dried is suspended in the fluid, thereby the two-phase contact area is large, has strengthened heat and mass transfer process, is widely used in the powdery of the industries such as chemical industry, medicine, building materials, the drying of granular material.
The drying of existing a lot of powderies, granular material generally is to dry by reaction pot, this drying mode material heating surface area is limited, simultaneously since its dry run in the open type environment, not only required drying time long, and have the shortcomings such as the thermal efficiency is low, environmental pollution, energy consumption height.
The utility model content
In order to overcome Shortcomings in the present technology, the utility model provides a kind of airstream drying tower.
A kind of airstream drying tower, described drying tower comprises feed arrangement, air-intake device, hothouse, deduster and drawing mechanism, described feed arrangement is arranged on a side of hothouse, drawing mechanism is arranged on the opposite side below of hothouse, described air-intake device is arranged on the below of hothouse, and deduster is arranged on the top of hothouse;
Described feed arrangement comprises charging aperture, batch charger and the material feeding box that from top to bottom arranges in turn, and material feeding box is communicated with hothouse;
Described air-intake device comprises air door, heat exchanger and the crosswind door that trunk line, several parallel vertical arrange, each air door upper end is communicated with hothouse by filter, each air door lower end is communicated with trunk line, described heat exchanger and crosswind door are arranged on trunk line one side and are communicated with trunk line, wherein, heat exchanger is near feed arrangement, and the crosswind door is near drawing mechanism;
Described drawing mechanism comprises discharging machine and is positioned at the vibratory sieve of discharging machine below that described discharging machine is communicated with hothouse by filter;
Described drying tower also comprises air-introduced machine, passes through the waste gas absorption pipeline communication between described drying tower and the air-introduced machine; Described waste gas absorption install pipeline is in a side of deduster upper end, and the opposite side of deduster upper end is provided with several impulse electromagnetic valves, and described deduster is communicated with hothouse.
Preferably, described deduster is sack cleaner.
Preferably, described hothouse external parallel is provided with row's visor, and described visor top is provided with several Pressure gauges.Observe in the convenient and dry process and control.
Preferably, described hothouse is provided with access hole away from an end of material feeding box.Be convenient to the maintenance of equipment.
Under air-introduced machine wind-force attracted, material can carry out even drying in hothouse, and waste gas attracts to discharge through air-introduced machine; Simultaneously, dusty gas enters in the sack cleaner, and under wind-force attracts, passes filter bag, and material is held back by filter bag, is deposited on the filter bag outer wall, and the gas after the filtration is discharged from the waste gas absorption pipeline.The sack cleaner upper end is provided with impulse electromagnetic valve, and when the resistance of sack cleaner arrived setting, impulse electromagnetic valve was opened automatically, utilizes air compressor machine that dust unnecessary on the filter bag is got off clearly, makes cloth bag keep smooth and easy, continuously operation.
The airstream drying tower method for controlling temperature inner is to regulate the hot blast intake by the aperture of damper, thus the tower temperature that acquisition needs.Simultaneously, generally should control air door during work and be reduced gradually to the discharge end aperture by feed end, so that hothouse air pressure is reduced to discharge end gradually by feed end, force like this powder in the hothouse to be moved to discharge end by feed end.Heat exchanger connects extraneous thermal source such as boiler etc., and cold air is heated to be hot-air, enters hothouse through trunk line, air door.The setting of crosswind door is very important, if do not have crosswind door or crosswind door to close, then the powder in the hothouse is difficult to be moved to discharge end by feed end, and may cause can't discharging.When the crosswind door is opened because that this place's air intake does not have through heating, temperature is low, thereby so that the hot blast of feed end move to the cold wind of discharge end.
The utility model is suitable for the chemical products such as dry polyamide (PA), Merlon (PC), polyethylene (PE) especially, and other powdery, granular material.
The utility model is simple in structure, and floor space is little, and is easy to install, also has simultaneously the heat transfer coefficient height, heat transfer area is large, drying time is short, the characteristics such as pollution-free.
